BENCH FOR SUPPORTING AND MEASURING BAR R TUBE LENGTHS AND FOR FEEDING 4 SAME TO CUTTING-OFF MACHINES.

Specification. of Letters Patent.

Patented Apr. 16, 1918.

Application led December 26, 1916. Serial No. 139,019.

To all 'whom it may concern.'

Be it known that I, GEORGE BENJAMIN TAYLOR, subject of the King of Great Britain, residing at Bartholomew street, Birmingham, in the county of Warwick, England, have invented certain new and useful Improvements in Benches for Supporting and Measuring Bar or Tube Lengths and for Feeding Same to Cutting-OE Machines, of which the followingis a specification.

The invention provides the hereinafter described and claimed improvements in and connected with a bench for supporting'and measuring a bar or tube length and for feeding same to a cutting off machine as, for instance, one described in the specifications of prior British Letters-Patent Nos.'25,233 of 1910 and 27,487 of 1913 to which the bar or tube needs to be accurately centered to the plurality of cutters.

The bench according to the invention is a rigidly built structure adjustable vertically to wholly raise or lower it and provided with devices for length measurement of the bar supported and to be fed, which devices include a clamp attached to the bar to be measured and adapted to be moved to a dierent position on the bar for each measure. The bar rests upon rollers disposed in fixed bearings of the bed, some of which rollers are positively revolved by hand operated means, said bar toward its forward end being frictionally gripped by a pair of rollers giving a positive feed. A cam action adjusts the height of the bed which normally lowers by its own weight if the cam action is relieved. The measuring devices comprise, in greater part, a rod secured to the bed, and two stops mounted thereon, a forward and fixed stop, and a rear and adjustable stop, the rod being set out with length measures.

A desirable arrangement of the invention is diagrammatically illustrated by the accompanying drawings.

Figure 1 and Fig.4 1a are a front elevation,

Fig. 2 and Fig.,2a are a plan,

Fig. 3 is a front end elevation, and

Figs. 4 and 5 are details of the clamp.l

, The bar ortube to be cut up rests upon live rollers a, b, c, d, and e disposed in fixed VZand e are followers revolved by the feed of the bar. The peripheries of all the rollers are slightly Vd to provide central seatings thereon for the bar. Y

The forward roller a is the lower one of a pair whose upper roller, a3is supported by a vertically movable frame, a4, riding upon supporting posts a5 a6 and traversed by a hand operated screw a7, the bar fc, indicated 1n Fig. 3, being frictionally gripped between the pair of rollers to put the necessary positive feeding pressure onto the roller a. The supports, a5, a, for the frame, at, are carried by an underframe, a8, adapted to rock at a on a pivoting to the bed, y, of the machine so that said frame can make a slight angular movement to accommodate inaccuracies in the formation of the bar gripped by the pair of rollers a a3, said frame however being generally supported by jortion of it resting upon a part 3,/2 Iof the All the lower rollers are supported upon the bed y which is bodily adjustable in a vertical direction to centralize varying diameters of bars to the axis of the machine. Said bed is provided by two channel sectioned lengt-hs g3 yt set opposite and parallel with their channelings outward and the rollers a, o, c, d, and c disposed in the space 315 between the channelings, the bottoms ofthe channelings, now disposed vertically, forming the necessary bearings fory the roller shafts. The two channel-sectioned lengths are eectively distanced apart by distancing pieces, fu, fw, through which transverse pulling up bolts pass, so that said lengths are Vee s., and, t, secured to any suitable foundation for supporting the bench, said upper ends being attached to the channelings 'by cross bolts f4 g4, the latter preferably Working in a slot of the pillars upper end. The underframes s and taredisposedone "near-each end of the bed, and they and a middle frame m form asupport ifor a 'longitudinal 'rocking shaft vt revolved from the 'collar n2 and carrying at n3 n4 two cams adapted by their p'eriplieries to '-contactfblccks a5 a6 suitably bolted across the undersidcs ofthe lower flanges of the two channel sectioned lengths. rlhe cams forni supports vfcr -the Whole of the vnu-aight of the 'bed 'y and Athe parts it carries, and they provide Vthe means for simultaneously lifting 'the bed at both ends to the sameextentso that ythe plane ofthe bed lis lalways in thevhorizontal plane, While the pillar and socket engagements y, f2, ggz guide'the truly vertical movement.

Extending-along the one side'of the-bed y parallel ytherewith is'a fixed measuring and stop carrying rod 'h set out With length measures as indicated by Figs. 2 and 2a. This rod has end bearings at h2 'h3 vWithin brackets suitably vbolt-ed tothe channel sectioned length g3. TWO 'stops z and jare'fitted to this rod, vthe l'former one a fixture, and fthe latter adjustable along lsaid rod. The adjustable stop ,7' is adapted 'for being clamped on lthe 'rod,`and is set thereon relativelto'the fixed stop tothe measure of the bar length tobe cutoff plus the amount of metal cut away by'the tools in cutting o'fl1 and plus 'the lengthof Ya clamp extensiono, hereinafter described, which measure is then the distance between the two stops. Said tivo stops `Whennearest are'always distanced the length of said clamp extension-0, as 'will beclea'r from Figs. l and 2.

The connecting piece between the bar to be measuredland the stops and y' is clamp Z, Figs. 4 and 5, adapted to be firmly but'detachably'att'a'ched -to the bar, w,`by the lrtwo screa7 :pins ZZ'ZS, said attachment being adjusted by the adjustable positioning abutment Z* of said clamp. rlhis clamp 'carries the extension 0 adapted lto contact Vthe vtwo stops and j, said 'extensionfbeingresilient in its-touch with the adjustable'stop AThe clamp is iiXed tothe bar'mwhileits eXten-V sion 0 is coi'it'acting the 'back stop j, andth'en the bar is-fed up by the'rolle'rs a, c, ,and @,through the operation of the'hand Wheel b2, "until the extension() contacts the -f'or- Ward' stop 2', Vwhich gives the necessary projection ofthejbar into thecutting'oif 'ma chine to' cut off the desired length fronrthe bar, the' ciampi being moved baclrtofa different ypart-of the bar -While AVeach *length is being cutoff ready forthe bar to'b'e fedup again tothe measure between thetWo-'stops z' and The resilient or spring vcon't'actof the extension o is provided by a plunger, o2, Working 1n a sleeve, Z5., of the clamp and spring operated in one direction by a coiled Y lspring o3 may be fully operative when the fclamp is being .placed on a dierent part of the bar with its end 04 hard up to the back stop j, during which time the fbaj-r fis fstationary, 'which nu't (05 -is afterward 'tightened up to a feeling Ltightness only, infthis Fway providing so v'that the lmeasure of vbar fed shall be always accurate -to the measure betweenthe twostops and The contact -o'f the extension@ 'Withthe stops l"is'a'lWays iat its ends only, *and the spring .pressure a'l- Ways insures touchlofis'aidlextensionat the end ot.
